The contents of the glass don’t matter; what’s more important is to realize there’s a pitcher of water nearby. In other words, we have the capacity to refill the glass, or to change our outlook.

Happiness is the precursor to success.

Habits are like financial capital – forming one today is an investment that will automatically give out returns for years to come.

Waiting to be happy limits our brain's potential for success, whereas cultivating positive brains makes us more motivated, efficient, resilient, creative, and productive, which drives performance upward.

I've worked with farmers in Zimbabwe who've lost their lands. I've worked with people in Venezuela, under threat of kidnappings, whose external world is unstable. But they have very strong social connections with their family and friends. And as a result, they're able to maintain a greater level of happiness and optimism than I've seen from bankers, consultants, or salespeople who are on the road all the time, who follow jobs separated from their families, and, as a result, find themselves missing out on the happiness that comes from those very connections that they severed.

Most people keep waiting on happiness, putting off happiness until they're successful or until they achieve some goal, which means we limit both happiness and success. That formula doesn't work.
